Steady, easy cardio while you work, logged straight to Apple Health.
What it is
Zone 2 is a steady, easy effort where you can still talk in full sentences. For some people a brisk walk on a walking pad, or a walk with a little incline, gets them there.
What the research says
“Zone 2” isn’t one universal number. Depending on the system, it can mean easy exercise in a five-zone scale, or the range between two breathing thresholds in a three-zone scale. (Jamnick et al., Sports Medicine, 2020)
- Easy cardio and fitness. A meta-analysis of 50 studies found that regular low-intensity endurance training improved VO2max, with large differences between studies. Harder training may give bigger gains. (Nuuttila et al., Scandinavian Journal of Medicine & Science in Sports, 2026)
- The talk test. Being able to speak comfortably generally means you’re at or below the first threshold, which is why it’s a practical guide.
- Walking pace. Around 5 km/h is often moderate intensity for adults, but the heart-rate zone it puts you in depends a lot on age and fitness. (Murtagh et al., Preventive Medicine, 2002)
How to try it
- Use the talk test. If you can’t speak a full sentence, slow down.
- Wear your Apple Watch so heart rate is recorded with the walk.
- Aim for 30–45 minutes, four days a week, at a pace you can type at.
- Look at trends, not single days. Resting heart rate and VO2max move slowly.
